Hope this is the right place to post a non-SpiceWorks related question...

I have a Dell Latitude laptop that will flash the screen for about 1 second when powering on, then turns black. You can see the screen but it has no backlight. Does anyone out there have enough troubleshooting knowledge on lcd's to know if this is because of the inverter, or do I need to replace the whole display (I'm not technical enough to try and replace the backlight even though I think the display itself is OK)

Dell Laptops typically have separate power and video connectors and cables that sometimes get loose or shorted. Location and routing varies to some degree, but generally a loose or shorted power connector can cause the symptoms you describe as well as a failed video chip on the system board. If it can display to an external monitor, then the video chip is good, check/replace cables. If no external monitor video (make sure you select external display with FN and applicable function keys), you need a new system board. If the cables are good, it is the LCD or backlight.
